The 3,3′,5,5′-tetramethylenebiphenyl tetraanion, prepared in good yield by metallation-elimination, gives tetrasubstituted biphenyl derivatives, e.g., with H2O, D2O, methyl iodide, and trimethylsilyl chloride. The reaction sequence, starting from alkylated cyclohexanones, provides a general synthetic route to symmetrical polysubstituted biphenyls.
通过金属化消除以高收率制备的3,3',5,5'-四亚甲基联苯四阴离子,得到四取代的联苯衍生物,例如与H 2 O,D 2 O,甲基碘和三甲基甲硅烷基氯。从烷基化的环己酮开始的反应顺序为对称的多取代联苯提供了一般的合成途径。
